My 15 month old dog has had a distinct lack of stamina for the last couple of weeks. He has always been walked about 3 miles a day and always wanted to go out, until recently. I have been playing ball with him and he seems to tire within 5 minutes and he pants very hard for a long time after. It has seemed to come on as the weather has really heated up into the 70's. I asked my vet when he had his annual booster and he didn't seem to concerned and it could be because he is having a little growth spurt but said to come back if it continues for another week.
Has anyone had any expierience of this.
